Flexxolutions GFS BV
About
Flexxolutions GFS BV, headquartered in Oldenzaal, Netherlands, manufactures sustainable technical textile products for the biogas, agriculture, horticulture, industrial transport, and humanitarian sectors. KIWA-certified and ISO 9001:2015-compliant, the company maintains full in-house production from raw material testing through finished product. Its biogas portfolio is anchored by the Flexxodomer double-membrane biogas roof for digester gas containment, the Flexxocover gas-open silo covering system that cuts ammonia and gas emissions by approximately 95% on silos up to 54 meters in diameter, and gas-tight silo roofs with integrated lung gas holders. The Flexxosphere provides spherical biogas buffer storage rated for pressures between 0 and +15.0 mbar, while Flexxovalve over/underpressure safety valves and Flexxocam leak detection cameras round out gas safety systems. For liquid and bulk storage, Flexxolutions produces Flexxobag flexible bags (100 to 7,000 m³), Flexxotank roll-out liquid tanks, Flexxosilo textile silos, and Truckliner internal liners for dust-tight bulk transport. The company also collaborates with UNICEF and Medecins Sans Frontieres on emergency WASH products including the Flexxotoilet, Flexxoshower, and Flexxobladder drinking water storage tank. A localized web presence spans six European languages.
